Though ‘How I Met Your Mother‘ hasn’t exactly gotten far into its final season wedding weekend, the guest list for the big event continues to swell with familiar faces. ‘Dawson’s Creek’ vet and former ‘Don’t Trust the B‘ star James Van Der Beek is the latest ‘HIMYM’ alum to reprise their role, while this coming Monday sees a fresh turn from ‘True Blood”s Anna Camp in the latest previews!

Having played Robin’s balding Canadian ex-boyfriend Simon in several episodes past, Van Der Beek shared over Twitter that he’ll pop up in the twelfth episode of the season, “Bedtime Stories.” It remains to be seen if the character will pop up in Farhampton or in flashback, given that we know Robin Daggers (nee Sparkes) will also return in flashback for an upcoming episode with ‘Karate Kid’ star Billy Zabka.

Elsewhere, CBS has released the first clip and full set of photos from Monday’s all-new installment “Knight Vision,” which features ‘True Blood’ star Anna Camp in the role of “the world’s worst wedding guest.” Says CBS of the episode:

“Knight Vision” — When Ted finds himself with three prospects to be his date for the wedding weekend, he chooses poorly. Meanwhile, Barney and Robin have a confrontation with their minister, and Marshall learns more about his driving companion, Daphne.
